"""Profiles dashboard routes (extracted verbatim from web_server.py).

Two routers because the original registration points are far apart and route
order matters: ``sessions_router`` (/api/profiles/sessions*) was registered
long before the generic ``/api/profiles/{name}`` routes on ``router`` — if the
literal-path routes were appended after ``{name}`` in one router, Starlette
would still match literals first here, but we preserve the original global
registration order exactly rather than rely on that.

Handler bodies are byte-identical; web_server-owned helpers are reached via the
late-binding seam in :mod:`hermes_cli.web_deps` so tests that
``monkeypatch.setattr(web_server, "_helper", ...)`` keep working.
